setNotificationIcon method
Set a custom IconTitle
to be displayed in the notification bar for the chathead.
Please note that in some cases, this is gonna ignore any asset given, and instead
use the default icon launcher.
Implementation
Future<String> setNotificationIcon(String assetPath) async {
final int result = await (_platform.invokeMethod(
'setNotificationIcon', assetPath) as FutureOr<int>);
return result > 0 ? "NotificationIcon set" : "There was an error.";
}
